We have a name for people who don’t care at all what other people think: sociopaths. It’s healthy to give at least some weight to that input.
Like the article says, lots of people get rich promoting very bad advice.
Society, as it is, is not the end all be all. What is socially acceptable, and what is not, is always evolving. People who were right, are now wrong, vice versa. I think people should prioritize selfishness and educating themselves. Don't be a slave, and question your own thinking patterns and habits. 90% of the comments are people not thinking for themselves. This article brought this issue to light quite vibrantly... Cheers.
